Okay, no problem.
There are a thousand free and for-purchase nondisclosure agreements (NDA in the trade) available online. You can google them just by typing in "non disclosure agreement." However, any large company will insist on their own agreement. So, you can call the company up and ask to speak to someone in marketing or creative development, and try to convince them to see you.
The problem is that they won't want to see you until you tell them what you've got, and you can't tell them what you've got unless they want to see you!
Anyway, most new creative inspirations are rejected. Hewlett Packard told Steve Wozniak, the inventor of the Apple One computer, that they weren't interested, and he was an employee. So, he and Steve Jobs started building them in their garage.
Similarly, Bill Gates started Microsoft by developing a simple Basic language interpreter that would fit on a microchip. But, the only reason why IBM purchased the child, was because Bill Gate's dad was a corporate attorney with connections -- otherwise Billy would never have even gotten past the front door.
Philo Farnsworth was the inventor of the color TV.He was an employee of RCA. They stole his invention, and it took him nearly his entire life to get any money for it. He died in relative poverty.

If you research the subject for a while, you will quickly discover that it is almost NEVER the case that someone obscure from outside of a large company comes in and convinces the company to purchase an idea. The only place that happens is in the movies.
Not trying to burst your bubble, but if you've got something good that absolutely depends on an existing product, then it's highly unlikely that you will be able to engage the manufacturer without someone else who is connected in the company.
Anyway, I realize that I'm not helping you here. BotXXXXX XXXXXne: a "nondisclosure agreement "is what you want.
